Two species of e have been 
found growing as escapes in southern 
Louisiana west of the Mississippi River. They may be expected east of the 
river. The genus differs from other menue of the iris family in the one- 
sided inflorescence and the curved and oblique perianth. G. segetum Ker- 
awl, native o e Mediterranean region has a rose-magenta perianth; the 
sepals and petals are clawed, the three upper blades ack have a median whitish 
e h 
-erimson. G. hortulanus Bailey, native of southern Africa, has a scarlet to 
vermilion perianth; the sepals have a red-brown median line and minute brown- 
minute specks and are often minutely pointed, the three lower blades of the 
perianth are yellow on the basal two-thirds and only searlet-bordered.
